Principles of acarology

The Acari, comprising mites and ticks, form one of the largest and biologically most diverse groups of the Arachnida. They are worldwide in distribution and rival the insects in the extent to which they have successfully colonized terrestrial and aquatic habitats. Some are significant crop pests, while ticks are parasites on a wide range of vertebrate hosts. This diversity of modes of life is reflected in their morphology and life-history strategies. This book provideds a detailed introduction to the Acari, concentrating on their functional morphology, but also covering their classification and economic importance. It will serve as a text and reference for acarologists and advanced-level students taking courses in general entomology (which traditionally include acarology), invertebrate zoology, and agricultural, medical and veterinary 'entomology.'
